Examples of single player games that use modern ML techniques in the AI?
There is Google Research Football, which is an open-source platform to develop reinforcement learning algorithms to play a game similar to FIFA or PES, although the football simulation is not as realistic as the current versions of FIFA or PES. You can play this game against different RL agents (e.g. DQN or IMPALA) and, of course, you can even develop your own RL agents and play against them. Here is a video that illustrates the environment. Here is the code and instructions to use it.
As far as I know, there isn't yet an AI that plays simulated football at a human-level (i.e. as good as the best human players). For example, I can regularly (although not always) beat the legendary level-AI at FIFA, but I also don't know the details about this AI (which could also be rule-based).
